This. invention. relates to restrainingdevices especially adapted for use holding sliclable windows against rattling.

More specifically. 'the invention contemplates a window restraining device.- in which the. window contacty element is mounted for movement in a more o-r less arcuate pathand isyieldingl'y held in. an intermediate position so that tbe same may rock in either direction in response to raising or lowering of theA dow and is. caused to have effective pressure Contact with the window at all times..

'A window restraining device, embodying the invention will, also be iound to provide novel means by wh-ich the window contact element is yiel'dingly heldin a; predetermined positionin pressure Contact with the glass against the contrary influence incident to the stresses transmitted through the glass when the motor vehicle equipped wit-li the device is in rapid motion or. is travelling over rough roads.

Another aim of the invention isto provide a restraining` device for windows vvlliicl'i, al1 though primarily designed torl installation during the manufacturey of an automobile, may be applied' at any time thereafter without marring the appearance of the vehicle or material change in design.

Other objects, and advantages will be apparent during the course of the following description.

In the drawings wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numerals 5 designate spaced' frame members defining a compa-rtment for the reception of a window 6.

Asillustratedin- Figures l and. 4;',the spaced frame members 5 may be provided with opposed sockets forthe reception of the restraining devices. Although a. pair of they` improved restraining devices. arev show-ni, oner on each side of the window it` isv clear that.-

one alonemaybev employed and.. `since each. of the restraining devicesy are alike,l the description of oneI will. be, foundz. to. suiiicel for both.

EachV restrainiI-igA device is provided with a base 8 having suitably spaced apertures 10 for the passage of fastening screws or other means by which the base may be mounted as shown in Figure 1. More specifically, the base 8 is adapted to be secured to the inner upright side walls of the socket in which it operates.

As shown in Figure 8, the base 8 is provided along opposite longitudinal edges thereof with upstanding ears 12' receiving the terminal portions of a pivot pin 14. It is shown that the ears 12 are provided with slots 15 extending at right angles to the plane of the base and freely receiving the terminal portions of the pin 14 so that a pivotal and sliding connection is provided between the pin and the base, such connection being for a purpose that will hereinafter appear.

Figure 8 also illustrates that a` carrier 16 is provided with a pair of spaced parallel flat legs 18 located between the years 12 and mounted on the pivot pin 14. .The outer portion of the legs 18 of the carrier 16 are joined by a roller piny 20 uponwhich a roller or window contact element 22 of rubber or other yieldable material is mounted. With reference to Figures 1, 4 and 7, it will be apparent that the window contact element 22 is mounted to freely-turn on the supporting pin 2O thereof so that the roller may rotate freely in response to the raising and lowering of the window 6. The sides or legs 18 of the carrier 16 are joined by a transverse connecting member 26.

From Figures 1, 4 and 7 it will also be apparent that the windowcontact element y22 is mounted for movement in an arcuate path so as to respond readily to intentional movement of the window and as brought out in the opening paragraphs of the specification, the. window contact element is yieldingly and normally held in an intermediate position in engagement with the window. In explaining this` attention is invited to Figures 5 and 8 in which it is illustrated that oppositely wound helical springs 32 and 34 are mounted on the pin 14 and are provided with arms engaging the hase and the .carrier 16. The base engaging armsof the helical springs 32 and 34 are anchored in place through the medium of fastening elements 38 that may be in the form of Aeyes struck up from the base although, it is obvious, that any means found expedient may be employed ,to hold the base engaging arms of the springs 32 and 34 in place. y

It is clearly illustrated in Figures 5vand 8 that the outer end of thespring 32 is provided with anv arm 40 vengaging alug 42 eX- tending from one edge of one of the side members 18 while the other spring 34 has the outer portion thereof Vprovided'with an arm 48 engaging the transverse connecting member 26. As previously stated, the helical springs 32 and 34 are oppositely coiled and when properly tensioned by the connection of the arms thereof to the base and to the carrier as clearly shown in Figure 5, will hold the carrier approximately at right angles to the plane of the glass.

As might otherwise be expressed, the pivotally mounted glass contact roller 22 is movable in an arcuate path by reason of the pivotal mounting of the carrier thereof and is normally held in what might be said to be an intermediate position through the employment of the oppositely coiled springs 32, one of which acts against the contrary influence of the other. By thus mounting the glass contact element 22, thersame may be rocked in either direction in response to the raising or lowering of the window.

That is to say, the window contact element 22 and more particularly the carrier thereof is pivotally mounted and is yieldingly held in an intermediate position so that the same may rook in either direction to allow of the passage of the clip 50 which binds the lower edge of the window. v

It might be added that the outer side of the channel shaped clip 50 is provided with a fastening strip 54 having the upper portion thereof offset outwardly to cooperate with the adjacent portion of the clip 50 in the formation of a channel or groove for the reception of the attaching portion of a rubber gasket 56, the latter being adapted to engage an overhanging portion 58 of thewindow frame to cooperate therewith in excluding water from the interior of the vehicle body or door in which the Window is located.

With further reference to the mounting of the carrier 16, it is pointed out that the slidableconnection between the carrier and the base, brought about by the provision of the slots 15, allows the flattened rear ends of the side members or legs 18 to atly engage the base so that the carrier is normally held perpendicular to the window against the contrary influence of thestresses incident to travel of the vehicle equipped with the restraining device. That is to say, rapid travel of the vehicle or movement of the same ,over rough roads is conducive to rattling or vibration of the windows and this in turn tends to rock the carrier 16 notwithstanding the presence of the helical springs 32 and 34. The squared rear ends of the legs 18 are held flatly and yieldingly against the base 8 by a -z leaf spring 60 shown-to be anchored to the base and having one terminal portion thereof curved about the intermediate portion of the pin 14. Clearly, the spring 60 urges the squared ends of the legs 18 flatly into engagement with the base so that the carrief` is normally heldat right angles to the plane of the window. When the window is raised or lowered, a protruding portion thereof such, for example, as the clip 50 may easily menigeen' pass the roller 22 since the carrier'- 116i is mounted toyielfd in. eitherdirection;

A window restrairrifng` device constructed in accordance with; this invention may be' applied* with: facility to the locationsl shown; in Figure. l or tof other places. where the same may' bei employed? to advantage. More particularly, the` device may? be appliedl either during manufactureY ofthe automobile orat any iinietliereafter and provides a simple and durable means` by which: the. tendency of: the window to rattle ifs effectively coinbated'. The employment of the improved restrain:- ing devices does not' in any way interfere with the motion transmitting means by which the window is raised through the Inanual operation of a crank or the like, it being apparent that the member 68 is employed in connection with the raising and lowering mechanism.

In summarizing, it will be seen that the invention embodies a Window contact element which is pivotally and at the same time slidably connected to a supporting means and is yieldingly held between the ends of the arc in which it moves so that the same is free to rock in either direction in response to raising or lowering of the window, there being means by which ordinary vibration of the glass as distinguished from the actual raising and lowering of the glass is prevented from rocking the glass contact element. Of course, since the roller 22 is of rubber or other yieldable material this part may yield the required extent 2:1 response to minor vibration of the glas* and in that way avoid the rattle that woul otherwise take place.

Having thus described the invention, what is claimed is:
